ok so the sum of angles inside a quadrilateral is 360 degrees, so all the angles have to add up to be 360, what does this tell you about the 4th angle?

anonymous · Answer

it need to be equal to 360 also

anonymous · Answer

i gave u a medl also

anonymous · Answer

nope, so what we have is 60+95+150+x=360, so you have to subtract each of those angles from 360 and what you have left is the fourth angle

anonymous · Answer

45
